Because there is no need for it.
When the vectors (bold) i, j, k are defined to be the standard basis vectors, 
then they are already unit vectors. Putting a hat over them is quite 
superfluous. That there is no easy way to do this in Unicode is surely 
indicative that standard usage does not require it, so you should be 
discouraged from attempting to do so.

And putting a non-bold hat over a special symbol that is already defined to be 
a unit vector would be quite redundant, adding no extra meaning.

I would advise against trying to do so.
Use the symbols provided in Asana, with their correct Unicode code-points. 
Then as future software is developed that better handles both the appearance 
and meaning of mathematical symbols, your expressions from PDFs that you are 
generating now will be useful to convey the meaning and semantics of your 
mathematics, not just it's visual appearance.

Hello,

To the best of my knowledge Unicode defines only
LATIN SMALL LETTER DOTLESS I (U+0131) and 
MATHEMATICAL ITALIC SMALL DOTLESS I (U+1D6A4) and for
both characters there are glyphs in Asana-Math. There
is no MATHEMATICAL BOLD SMALL DOTLESS I symbol or even
a MATHEMATICAL BOLD ITALIC SMALL DOTLESS I.

No. See the e-TeX documentation for more details about \beginR, etc.

Not if I recall correctly - left is still left, and right is still right.

Don't I need to put \endR somewhere so that it's balanced?

Ok, that's clear. Will \leftskipt and \rightskipt then be quasi switched too?

Don't put all that stuff at the end of the paragraph! For a standard RTL 
paragraph, you want to still be in RTL mode when the \par is encountered.

So, try:

\noindent \beginR \indent Lorem ipsum dolor sit amet, consectetur adipiscing 
elit. Mauris luctus accumsan vulputate. Vivamus vel lacus nunc, a dictum lacus. 
Duis rutrum, odio blandit dapibus facilisis, ipsum neque vestibulum ligula, ut 
vulputate leo nisl eget dolor. Donec luctus consequat porta. Duis tristique 
elit in sapien vulputate non pulvinar felis interdum. Praesent auctor eleifend 
sollicitudin. In hac habitasse platea dictumst. Donec congue congue interdum. 
Suspendisse vel dictum nulla. Nullam sit amet mi ut libero blandit 
scelerisque.\par

Or just precede a series of paragraphs with:

\everypar={\setbox0=\lastbox \beginR \box0 }

for automatic RTL-ness. (Explanation: \lastbox is used to retrieve the box that 
was inserted for the original automatic (LTR) paragraph indent; then after 
switching directionality, we put it back again so as to get the indent at the 
right end.)

Ok, I found, that the following sort-of does:

-
\parfillskip=0pt\parindent=0pt
\leavevmode\beginR \hskip 8em Lorem ipsum dolor sit amet, consectetur 
adipiscing elit. Mauris luctus accumsan vulputate. Vivamus vel lacus nunc, a

congue congue interdum. Suspendisse vel dictum nulla. Nullam sit amet mi ut 
libero blandit scelerisque.\hskip 3em plus 1fil\nobreak\hbox{}\break\endR
\par

\leftskip=0pt plus 1fil% simple ragged-right paragraph
\parfillskip=0pt\parindent=0pt
\leavevmode\beginR \hskip 8em Lorem ipsum dolor sit amet, consectetur 
adipiscing elit. Mauris luctus accumsan vulputate. Vivamus vel lacus nunc, a

[XeTeX] RTL paragraphs with XeTeX?

[Petr Tomasek]

Hello!

Does anyone know of a simple example of how to do RTL
paragraphs in XeTeX (no XeLaTeX or bidi package etc.!)

What does the trick? I tried to fiddle with \parfillskip,
\leftskip, \rightskipt or \hangindent/\hangafter but didn't
find any reasonable way to do this.

Or is there some new XeTeX primitive (other than \beginR / \endR)?

Again, please, don't write me about XeLaTeX, I'm not interessted in
it.

Thank You!

Re: [XeTeX] Bold unit vectors

[Tobias Schoel]

Yes, it seems as if Asana doesn't support \imath / U+0131 in Bold.

The \hat shouldn't be printed bold, as it wouldn't look good and the 
bold/regular difference wouldn't carry meaning.
